MIDIBox SpeakJet K64 Modul
Introduction
K64 Modul is seperated in 2 Applications - K64 and K2 SpeakJet Application:
K64 Application is a classic keyboard-controller to play MIDI Notes from retro C64 keyboard for
seperate UPPER- and LOWER-Keyfield Input. You can control MIDI events for specific channels too. So
you can use it as mobile input device for external syntheziser or to use it as input keys for SEQV3
application. With an additonal seperate SpeakJet Modul you are able to control parameters for
SpeakJet and SEQV3 at same time.
If a SpeakJet-Board is installed you can use the advanced functionalities “Text To Speech” Mode. This
Mode allows you to write text phrases, which are processes directly in realtime by setup variation,
speed and bend for every letter of a word/sentence. Text To Speech can be controlled via incomming
MIDI Notes in several modes. Every letter can be replaced by variations in Realtime. German
language is pre-configured.
All Text To Speech patches can be stored up to 8 external EEPROMs on a bankstick. 2048 patches
(8x32k) or 4096 patches (8x64k) are maximum possible.

Warning / Notes
Use the hardware build up at your own risk! Use the applications at your own risk! I will not liable for
any damages at hardware or software.
For SpeakJet-Board PIC16F88 the SpeakJet firmware 1.0 should be sufficient. (It works fine about a
year). AudioCommander noticed some errors with his build-up, so he have done some changes in
released 1.2 firmware.
Please read all information about PSU, PCB Boards (CORE, SpeakJet / K2, C64 Keyb etc.) at MIDIBOX
WIKI and Ucapps.de. See links above.

The main screen - the midi keyboard
The main screen - the midi keyboard
The main screen displays the adjustable midi settings to use the C64 keyboard as a splitted
midikeyboard with UPPER and LOWER Keyfield. Maybe you can use it to play or control external
device (SEQ, Syntheziser, K2) seperatly. I'm often using the LOWER keyfield to transpose SEQ tracks
and SpeakJet pitch at same time by SEQ's internal router. Maybe the UPPER keyfield can be used for
playing notes or chords directly.
Playing notes
In the middle of screen the current playing midi notes are displayed. Notice that only 3 keys are

possible at the same time. That's a restriction of the keyboard matrix, because pushing a 3th key in
same row/col will short-circuited some other keys in matrix. To solve that problem as good a possible,
i've implemented an additional HOLD Mode (press RETURN and a “+” will be shown besides CH1). It's
easier to play chords and to hold them without holding down all the keys. In HOLD Mode an additional
4th note can be played in the lower Keyfield too - so 3th chords in the upper field and e.g. a bass line
in the lower field can be played and changed at same time. You can release all notes by pressing
CTRL. You can switch off HOLD Mode by pressing RETURN again. The state of HOLD Mode will be
stored internal.
If a played chord is known, it will be shown on the left side of note view:
Play chords / notes in a simple way:
Setup keyfields
On the right side of screen the adjustable channel- and transpose-values for UPPER and LOWER
keyfield are shown. CH1 (for LOWER keyfield) can be changed with CRSR keys up down, CH2 (for
UPPER keyfield) is variable by + and -. Pushing F1 and F7 will change the transpose value (TR1). For
the UPPER Keyfield TR2 is adjustable in 2 ways: Pushing SHIFT_R + F1 and SHIFT_R + F7 or pushing
simply the SPACE key. A short touch of the space button transposes TR2 up, a longer touch
transposes TR2 down. All Parameters will be stored internal.
CCs and Values
On the right side of screen the adjustable CC and CC Values are shown. The pointer char “>” infront
of Midi-Channel presents the current Channel for a choosen CCs. SHIFT_R + ? switches the CC pointer
between the 2 keyfields. CCs are adjustable with F3 and F5. The Keys COMMODORE and SHIFT_L

presents the datawheel of K64. CC Values are sended out by moving CC Value up and down with that
keys. INST/DEL Key sets values back to 0.
Triangle LFO
There is an integrated LFO option to automate some functions of the datawheel. The LFO option
changes the CC Values in a specific interval up and down. Close to CC Value area, there are 2 marker
adjustable. The Startpointer “>” on the left and Endpointer “<” on the right side. The Start marker is
adjustable by pushing SHIFT_R + LIRE key - the end marker by SHIFT_R + CLR/HOME. Changes adjust
the border for triangle LFO. SHIFT_R + “-” Key resets default marker position (0..127).
To Start the LFO press RUN/STOP. To Stop the LFO press RUN/STOP again. You can influence the flow
by controlling CC Values manually, changing end- and start-position and setup Speed Value.
Start Marker:
End Marker:
Speed option
The speed value (default = 1) behind the value number presents the speed of changing CC Values,
which are controlled by datawheel or by LFO. Manual changes are constantly double fast as LFO.
Pushing SHIFT_R + F3 or SHIFT_R + F5 will change the speed value. Notice, if the speed value is 0 the
LFO will be frozen.
Union Mode
The Union Mode binds the lower and upper Keyfield. All notes will be sended out to the single Midi
Channel.
SEQV3 Record
People, which own's a MIDIBox SEQV3 are able to use this special feature to record or to modify
parameters as easy as possible from K64. Every step of a track can be controlled by Cursorkeys,
toggling notes (Space Key) or recording notes from Keyfield.
The Record Mode is available by pushing SHIFT_R + RETURN in mainscreen. Note!! Only SEQ
versions higher than SEQ V3.2a will work correct. All you have to do: Set up the same
midichannel for SEQV3 midi-in and K64 (lower) keyfield.

Tracks can be copied by pushing SHIFT_R + UPARROW (Copy) and pasted by pushing SHIFT_R + @
(Paste). Pushing first time will activate the COPY / PASTE MODE (so you can use the rotary encoder of
your SEQ to select an area); Pushing same keys a second time again - the selected area will be copied
or pasted. Try it out.
For choosing another track you have to push SHIFT_R + F1 / SHIFT_R + F7 for step tracks up or down.
If you want to choose one of the 3 layer push SHIFT_R + F3 / SHIFT_R + F5.
Keys like + or SHIFT_R + “+” will activate the SCROLL or MOVE MODE.
CLR/HOME will clear a track; INST/DEL will undo a command.
It's possible to start and stop the sequencer with “]” and “=”.
RETURN will toggle between REALTIME and STEP feature of record mode. I've used the STEP MODE for
recording a note at current position, while a track is playing. So now it's possible to listen up the track.
LIRE Key toggles between the AutoStart feature of record mode.
Available SpeakJet areas
If you've installed the K2 and SpeakJet-Board and if you want to control the SpeakJet for Text to
Speech, you can change the main screen to TTS screen by pushing CTRL. If you press CTRL again, you
will be back in main screen.
If you want to change SpeakJet CCs instead all CCs, press ←.
If you push SHIFT_R + ← you will change to Synth Mode of SpeakJet. Push ← again, you will turn back
to main screen.
SpeakJet K2 Parameters
SpeakJet Parameters are: (OS1…5) pitch of OSC 1,2,3,4,5; (VO1…5) volume of OSC 1,2,3,4,5;
frequency of Envelope (ENV); Distortion-Level of OSC 4 and 5 (DIS); global Speech Speed (SPD);
global Speech Bend (BND); Jaw (JAW) and Tonque (TON).
Remember SpeakJet control is only available, if K64 modul is linked to K2 modul via MIDI.
SpeakJet Configurations
The SpeakJet can be configured with following Keys:
SHIFT_R + E toggle Envelope Type (saw, sin, tri, sqr)
Toggles Envelope Type will only be shown on K2 Display. Parameter E changes to several waveforms.
SHIFT_R + T toggle Envelope State (0,1,2,3)

2020/11/16 14:09 7/15 MIDIBox SpeakJet K64 Modul
MIDIbox - http://www.midibox.org/dokuwiki/
Toggles Envelope State will only be shown on K2 Display. Parameter T changes to 0,1,2,3.
Bit 1: activates Envelope for OSC 123
Bit 2: activates Envelope for OSC 45
So T = 3 will link all OSCs to the Envelope.
SHIFT_R + O toggle OSC for OSCSynthese
Toggles OSC Waveform for OSCSynthese.
If something goes wrong, or something isn't adjusted right with SJ anymore, it's possible to reset the
speakjet with key combination SHIFT_R + ←.
Some more function for configuration the SpeakJet are described on keymap.
Talk Mode
If Talk Mode enabled (SHIFT_R + = ) then the current selected text patch will be sended out by
pressing keys on the lower keyfield. You can play the correct tone scale at Midi Channel 4.
How to create TextToSpeech Patches?
First we changed from mainscreen to TTS Screen by pushing CTRL. Now the first patch will be shown.
If nothing is stored before, only a blinking cursor will be displayed. Now you can write a word or a
sentence. Notice that the application is preconfigurated for german language (because german words
are easier pronounceable from text as any other language. E.g. english are very different between
written letters and spoken text - many algorithmics have to be implemented to meet all requirements
for a TTS).
Ok, we will try to write a german sentence:
Der Weltraum example
The upper line is for writing input (max. 32 characters for patches are allowed). A space character will
insert a pause. The cursor can be moved by CRSR Keys to a special position in word. On the left side
you can choose the current bankstick (SHIFT_R + F1 / SHIFT_R + F7) and the current patchnumber (+
/ -). The lower line represents different configurations for every letter.
Text modifications
LIRE - delete
INST/DEL - backspace

SHIFT_R + INST/DEL - insert
CLR/HOME - Pos1
SHIFT_R + CLR/HOME - Clear
RETURN key or any MIDI-IN Notes at Channel 13 or Channel 14 (bended) will send out the phrase.
Midi-IN Channels 1..12 are used to activate the text patches of bankstick.
Speech modifications
Ok, we should fine tune pauses in sentence. Go to the space positions and write down a number or
using F3 / F5 keys. Higher values will insert longer pauses. Try following:
Ok, we should fine tune variations of letters. We change the letter “E” in “WELTRAUM” and the first
“E” in “WEITEN”. Use F3 / F5 to change numbers below letters and listen to the result:
Der Weltraum with pauses and variations
Every letter can be changed by variations. The number of variations is different for every letter. Try to
find out the best combinations for your words.
Now we want to do changes in Speed and Bend. Pushing F1 / F7 will change “VAL” to submenu
“SPD” and “BND”. Try to added following changes in both and listen to the results by pushing
RETURN:
SPD and BND settings will change global settings for SpeakJet. So next speakjet events (e.g. next
spoken letter) will use the last values for Speed and Bend. The normal value for Speed is 8 and for
Bend 4.
Storing Patches
At least you are able to store the patch on current patchnumber by pushing SHIFT_R + RETURN. A
Message will be shown. Every 32K Bankstick can store 256 Patches; 64K Bankstick can store 512
Patches.
If you want to copy the text phrases to another position: Hold down SHIFT_R and choose the new
patchnumber by + / - keys. Notice, old patches will be overwritten.
Using Textphrases
There are several modes to controll Textphrases:

1. Pushing RETURN in TTS Screen and Mainscreen plays the actual patch
2. Incoming MIDI Notes can used for playing phrase in several modes:
for 32K Bankstick you can use patches:
CHANNEL 1: C-1, C#1... Patch 1,2...
CHANNEL 2: C-1, C#1... Patch 51,52...
CHANNEL 3: C-1, C#1... Patch 101,102...
CHANNEL 4: C-1, C#1... Patch 151,152...
CHANNEL 5: C-1, C#1... Patch 201,202...
CHANNEL 6: C-1, C#1... Patch 251,252...256
for 64K Bankstick you can use additional patches:
CHANNEL 7: C-1, C#1... Patch 301,302...
CHANNEL 8: C-1, C#1... Patch 351,352...
CHANNEL 9: C-1, C#1... Patch 401,402...
CHANNEL 10: C-1, C#1... Patch 451,452...
CHANNEL 11: C-1, C#1... Patch 501,502...512
Text patches will be played as in describtion above in mainscreen. So you can trigger whole
sentences with incoming midinotes from a SEQ. Let him sing while sending additional notes to
CHANNEL 4 of K2.
If you are in TTS screen, only the fit note will play the current patch. E.g. TTS screen displays PatchNr
3 then only D-1 will trigger the text phrase. All other notes will be ignored.
CHANNEL 13: Plays actual text patch
CHANNEL 14: Plays actual text patch with changing BEND
C-1, C#1... BEND 0,1,2,3,4,5...127
